A curable material delivery cannula device (25) is disclosed. The device includes a cannula and a hub. The cannula includes an open proximal end, a deflectable segment (88) forming a pre-set curve, a lumen, and side orifice (s) (84) adjacent, and proximally spaced from, the distal end and fluidly connected to the lumen. When inserted within a guide cannula, the deflectable segment straightens. When distally extended from the guide cannula, the deflectable segment reverts to the curved shape. The distal end has a blunt tip for non-traumatic interface with bodily material. During use, curable material, such as bone cement, is delivered from the side orifice (s) in a radial direction relative to the lumen. |
